[time-nuts] SI5328

In my opinion the SI 5328 is worth looking at for time nut application, like offset frequency. My problem is solder ability. Does any one know a source for an evaluation board or as an alternative a source that would do a small volume assembly? Bert Kehren

Re: [time-nuts] SI5328

There are many small volume assmebly houses available. But the problem is that you will have setup costs in the order of at least 100-300€, even if you go to China. So, producing lots of less than 10 is not economical, probably should aim for 100. I recently ran across MacroFab
